The deadline for submission of proposals for the CNH competition has been changed to Friday, January 26, 2018. The deadline previously posted had been Tuesday, January 23. Proposals submitted prior to 5:00 PM (submitter's local time) on Friday, January 26, 2018, will be accepted. This change has been made because FastLane and other NSF systems were unavailable for three days from January 20 to January 22, 2018.

A revised version of the NSF Proposal & Award Policies & Procedures Guide (PAPPG) (NSF 18-1), is
effective for proposals submitted, or due, on or after January 29, 2018. Please be advised that, depending
on the specified due date, the guidelines contained in NSF 18-1 may apply to proposals submitted in response to this
funding opportunity.

SYNOPSIS

The Dynamics of Coupled Natural and Human Systems (CNH) Program supports interdisciplinary research that examines human and natural system processes and the complex interactions among human and natural systems at diverse scales. Research projects to be supported by CNH must include analyses of four different components: (1) the dynamics of a natural system; (2) the dynamics of a human system; (3) the processes through which the natural system affects the human system; and (4) the processes through which the human system affects the natural system. CNH also supports research coordination networks (CNH-RCNs) designed to facilitate activities that promote future research by broad research communities that will include all four components necessary for CNH funding.
